Description

[0001] BIO-AEROSOL CAPTURE DEVICE [0002]

The present disclosure relates to a bio aerosol collecting apparatus.

In the atmosphere, there are a variety of micro-materials besides air, including bio-aerosols, such as fungi, bacteria, pollen and the like, of biological origin. Bio-aerosols present in the atmosphere are emitted from various sources of indoor and outdoor environment.

Bio aerosols have been pointed out as the cause of air pollution and diseases, and the human body is acting as a cause of infectious diseases, allergies, respiratory diseases and cancer. Therefore, a technology for quickly and effectively detecting such harmful bio-aerosols is required.

Methods for detecting bio-aerosols include sampling bio-aerosols in the atmosphere, smearing them on a medium, culturing them to measure the number of colonies, and measuring the autofluorescence of microorganisms.

However, in the conventional method, it is necessary to directly measure the presence of microorganisms by sampling the surface of the food or the sample. When using the existing portable analyzer, the bio-aerosol can be directly detected A method of sampling the culture medium on the surface of the culture medium, culturing the culture medium, and measuring the number of colonies to be identified is used. That is, the method of counting the number of colonies by sampling the bio aerosol in air has a disadvantage in that it can not measure the bio aerosol in real time. The method of measuring the self fluorescence of microorganisms has a disadvantage in that it can detect in real time but the detection efficiency is low due to the very low intensity of autofluorescence. Therefore, in order to measure the intensity of such a self-fluorescence, expensive large-sized laser equipment must be used, so that the measurement equipment becomes large and high cost is required. Therefore, there is a problem that separate methods are required to efficiently detect the bio aerosol in real time in both of the above methods.

In this regard, Korean Patent Laid-Open No. 10-0871938 discloses a method for detecting and identifying bio-aerosol particles in air, but does not solve the above problems.

The open shape of the disk fixing portion 210 is not particularly limited, and may be, for example, circular or polygonal.

The pump 300 may be connected to the inside of the tubular body through which the bio aerosol collecting means 500 is positioned based on the disk so that the bio aerosol in the gas flowing into the tubular body passes through the through hole of the disk, Can be formed so as to flow to the communication part (310) on the side where the means is located. The pump may be formed to communicate with the inside of the tubular body by a plurality of communicating portions.

The pump 300 is driven by an electric motor to spontaneously suck air so that the gas introduced into the inlet 110 flows into the interior of the tubular body 100 and escapes to the communication portion 310 of the pump Function. The bio aerosol introduced together with the gas increases in flow rate as it passes through the through hole 220 of the disk 200 and is collected in the bio aerosol collecting means 500. The gas passing through the collecting means 500 is supplied to the pump 300 Through the communication part 310 connected to the pump 300. In this regard, the communication part 310 connected to the pump 300 is disposed on the opposite side of the inlet 110 with respect to the disk 200, passes through the bio-aerosol collecting device 500, It is preferable that they are disposed close to each other.

The communicating part 310 can be tilted and fixed to the tubular body 100 in consideration of the efficiency of the continuous gas flow until the gas is sucked from the inlet 110 and enters the pump 300. [
